Tears are essential to help you see clearly and maintain the health of your eyes. Unfortunately, patients with moderate to severe dry eye may not produce enough tears to remain comfortable, and supplementing natural tear production with artificial tears or lubricants is often inadequate. Many people have underlying medical issues which cause or worsen dry eye, including diabetes, rheumatoid arthritis and thyroid disease. Others take medications which diminish tear production. At Key Pharmacy we can work with your doctor to help find relief for patients with dry eye and to prevent long term damage to the ocular surface resulting from a lack of tear production.
